7 times what equals 15?

7 times what equals 15? In other words, what do you multiply by 7 to get 15? If "x" is "what" in the sentence, "7 times what equals 15?", then the equation to solve the problem is as follows:

7 • x = 15

Which can be written as:

7x = 15

To solve the equation above, we need to remove the 7 on the left side to make the x alone. To do that, we divide both sides by 7.

7x/7 = 15/7

7x/7 is x and 15/7 is 2.1429 which means our equation will look like this:

x = 2.1429

Thus, the answer to "7 times what equals 15?" is 2.1429.

To double-check our work, multiply 2.1429 by 7 to see that it equals 15. (Note that our answer on this page is rounded to 4 digits if necessary.)
